ElectriFly Cosmic Wind ARF Review

The Goodyear Trophy race is alive and well in the new ElectriFly Cosmic Wind ARF. Kurt and Rob put some nostalgia on the flight line and see how this little hotliner handles. See which way the Cosmic Wind blows on our 5X5 review…

Intro and Flight Footage
5X5 Review Scoring



The quintessential ARF, assembly rarely comes as textbook as the Cosmic Wind. All the right elements are there to get a builder up and going: a little epoxy, a little CA, some hinging, drilling, fastening, and wiring. When we finished the Cosmic Wind’s assembly, things couldn’t have gone more predictably.

If that wasn’t enough to get us a little excited about the flight, feeling how light the completed model was with a .10 size powerplant onboard had us eager to take to the air. Roll-out with the Cosmic Wind requires generous up elevator if you want to do anything more that ground loop in a slight cross-wind. There’s so much power and so little weight, you have to keep the tail pinned to the ground if you want to take off with some directional control. After a failed first attempt, and about 3/4 up elevator applied, we were able to actually get some ground speed before takeoff. Either way, the Cosmic Wind leaps into the air.

Our model required zero trimming and was immediately carving beautifully straight lines. With so much under the hood, half throttle flying is more than possible and runtimes are extremely generous. Inverted flight required little up elevator and maneuvers were very consistent. In the air the Cosmic Wind does everything you’d expect from a racer but remains so easy to fly at lower speeds you’ll find yourself thinking of it as a warbird trainer, a sport flyer, a pylon trainer, and a racer combined into one. The Cosmic Wind possesses an extremely wide low-wing flight envelope.

When it’s time to settle back to earth, the Cosmic Wind offers no argument. Enter into a nice glide slope, slight power on to keep the nose up and you’ll find the stout little landing gear sticking to the runway in no time. On the ground the little tiny tailwheel actually keeps you in control, making the Cosmic Wind a great flyer AND driver.
